Abstract

A power control system for communication systems which utilizes a ternary signaling scheme to reduce or eliminate limit cycling which occurs as the result of using a binary signaling scheme. The power control values (each having one of three possible values) are not encoded and are punctured onto the data to improve the response time of the power control loop and allow for dynamic adjustment of the transmit power. The power up, power down, and do nothing commands are represented by positive, negative and zero values (e.g., +1, -1, and 0), respectively. The remote station (6) decreases its transmit power if any base station issues a power down command, maintains its transmit power if no base stations (4) issue a power down command and at least one base station issues a do nothing command, and increases its transmit power if all base station issue power up commands.
